Toxicity to pets

Diuertics, often known as “water pills,” cause the kidneys to excrete too much water and salt (along with other electrolytes). These medications are commonly used in both veterinary and human medicine for cardiac disease or hypertension (high blood pressure). When ingested in toxic amounts, diuertics can result in severe dehydration, excessive thirst and urination, and rarely, even kidney failure. Immediate veterinary attention is generally required, depending on the amount ingested.

Common signs to watch for:

  • Severe dehydration
  • Excessive thirst and urination
  • Lethargy
  • Acute kidney failure (rare)
